App1ication filed February 7, 1910. Serial No. 542,519.

To all whom it may concern:

Be it known that we, Cosiio LIACI and ANGELO GIAMMATTEI, citizens of theUnited States-,residing at New .Haven, in the county 1 5 of New Havenand States of. Connecticut,

have invented a new and useful Means for Converting Motion, of. whichis'a specification;

This invention has reference to improvements in means for convertingmotion and inent -whereby rotary motion may be converted into continuousrotary motion or .in-

termittentrotary motion differing from the speed andpower of the primemover.

*" -The invention comprises a prime mover having a practically constantspeed .and means' for converting the motion so gener- 2 0 power, andalso into intermittent rotary moated intorotary motion of a differentspeedor speeds with commensurate available tion in different directions,and likewise provides-ineans for the storage ofpower until theaccumulated poweribeoomes greater. than the power ofthe prime moverandlis then. utilized either rapidly, or slowly in accord-' aiice-withthe workto' be performed.

The mechanism is reversible and therefore various types of motion maybeconverted into continuous rotary motion.

- The invention will be best understood from aconsideration of thefollowing detail description taken in connection with the accompanyiiigdrawings forming a part of 'this specification, inwhich drawings Figures1 and'2 taken together constitutea side elevation of the mechanismforming the subject matter of the present invention with some partsshown in section, the two figures over-lapping. together constitute aplan view of the mech- Figs. 3 and & taken anism shown in- Figs. 1 and2, the two figures over-lapping.

and 3 of an inertia structure used in connection with the HIVQHUOIL'Fig. 10 is an elevation of a portion of a lever mechanism used inconnection with the structure of.

Fi 1 f s b. I I q Referring to the drawings, there is shown a shaft 1mounted in bearings upon suitable standards 2 which may be supported ona the following this block being sustained by a pivot'pin 6 so as toswing into and. out of the pocket as may be necessary, to overcomesudden resistance to the rotation of the fly wheel. The block 5 carriesa spring? which when .the block is seated in its pocket 4: is undercompression and tends to move the block outward around its pivot pin 6.Each block is formed with a cavity'S normally entered by one end 9 of alatch lever 10 mounted on the side oft-he rim of the fly wheel 3 andunder the normal control of a spring 11 tending to'maintain the end 9 ofthe latch lever in the cavity 8 and so look the block 5 against movementabout its pivot pin 6 under the action of centrifugal force.

At the end of the lever 10 remote from the end 9 there is a roller 12designed to engage a fixed stop member 13 by which each lever 11 iscarried in the rotation of the respective fly wheel or inertia member 3.The member 13 is carried by a post 'or standard 14 and is so disposedwith reference to the respective fly wheel that when a lever 10 is movedpast thestop member 13 the lever is turned on its pivot against theaction of the spring 11 to an extent sufiioient' to withdraw the end 9of the lever 10 from the cavity 8 and so release the block 5 to outwardmovement under centrifugal force and the initial impulse given by thespring 7. At another point in the movement of the fly wheel there isasecond stop member15 carrying an anti-friction roller 16 in position toengage the projected block 5 and turn the same on its pivot pin 6 to itsseated position in the pocket 1 where itbecomes locked by the latchlever 10.

Mounted on the shaft 1 is a pulley 17 con nected by a belt 18 to anotherpulley 19 on ion 23 on the same shaft with a gear wheel 24 which in turnmeshes with a pinion 25 on a shaft with a gear wheel 26 meshing withanother pinion 27 on the same shaft with a gear Wheel 28 which in turnis in mesh with a gear wheel 29 on a shaft carrying another gear wheel30, and the last 7 named gear wheel 30 is in mesh with a gear wheel 31mounted on a shaft 32 having bearings in standards 33 erected on asuitable support which may be the same upon which the standards 2 areerected. The gear wheel 31 is in mesh with ,a gear wheel 34 on a shaft35 mounted in hearings on standard 36, and the gear wheel 34 is in meshwith another gear wheel 37 in turn mounted on a shaft 38 having journalhearings in standards 39. The gear wheel 37 is in mesh with a gear wheel40 mounted on a shaft 41 having journal bearings in' standards 42 andthe gear wheel 40 is in mesh with another gear wheel 43 mounted on ashaft 44 having bearings in standards 45. Also the gear wheel 43 is inmesh with another gear wheel 46 mounted on a shaft 47 having hearings instandards 48. The gear wheel 46 is in turn in mesh with a pinion 49mounted on a shaft 50 having bearings in standards 51 and also carryingfly wheels 52 against the rim of which there may be brought at will theactive end of a brake lever 53. The pur pose of these several gearwheels will appear hereinafter.

Mounted on the shaft 32 on opposite sides of the gear wheel 31 areone-way clutches 54, 55, 56 and 57, best shown in Figs. 6 and 7 where itwill be seen that each clutch comprises a casing 58 inclosing a ratchetwheel 59 fast on the shaft 32. In the inner wall of the casing 58 thereis formed a cavity 60 housing a pawl 61 urged toward the ratchet wheelby springs 62. When the casing 58 is rotated in one direction the pawl61 will ride idly over the teeth of the ratchet wheel and when thecasing is rotated in the other direction the pawl 61 will engage a toothof the ratchet wheel and the latter will participate in the rotarymovement of the casing 58. The casing of each clutch 55 and 56 carriesan arm 63 fast to the casing and having at its outer end a weight 64which may be as heavy as desired and much larger in proportion thanindicated in the drawings where the showing of the weight is simplytypical or diagrammatic. The tendency of the weight 64 is to turn thecasing 55 or 56 as the case may be in a direction to cause the rotationof the shaft 32. The weighted arm 63 is controlled by a lever 65 througha system of levers similar to a like system shown in- Fig. 2 and to behereinafter described, and the lever 65 has its free end in the path ofpins 66 on the hub of the gear wheel 34. Each time the gear wheel 34rotates the two weighted arms 63 are elevated, the correspondingclutches 55 and 56 moving inactively. As soon as the pins 66 pass fromengagement with the levers 65 the clutches 55 and 56 are released to theaction of the weights 64 and a rotative movement will therefore beimparted to the shaft 32 through a distance agreeable with the movementof the weighted arms.

The two clutch members 54 and 57 have their casing provided each with anarm 67 projecting radially therefrom and at the free end pivoted to apost 68 rising from a head 69 lodged in a casing 70 containing apowerful spring 71. The head 67 is provided with anti-friction rollers72 to ease its movement within the casing. The head 69 of each casing isprovided with another standard or post 73 to which is pivoted a lever 74at an intermediate point in the 'length of the latter, one end of thelever being pivotally secured to a fixed post or standard 75. The end ofeach lever 74 remote from its supporting post 75 is pivoted to anotherlever 76 which in turn is fulcrumed to a fixed post 77 while the otherend of each lever 76 is in the path of radial arms 78 rotatable aboutthe axis of the shaft 32, these arms being supported by said shaft butnot secured thereto. The arms radiate from a hub 79 carrying at the endremote from the arms a worm wheel 80 engaged by a worm 81 on one end ofa shaft 82 having journal bearings in a bracket 83 carried by arespective standard 33. It will be understood that there are two wormwheels 80 and worms 81 with their shafts 82 on opposite sides of thegear wheel 31. Each shaft 82 terminates in a bevel gear wheel 84 in meshwith a mutilated bevel gear Wheel 85 on the respective ends of a shaft86 mounted in suitable bearings on the upper ends of standards 87. Theshaft 86 carries a pulley 88 connected by a belt 89 to a pulley 90 onthe shaft 1.

Power may be applied to the shaft 1 by means of a belt 91 travelingabout a pulley 92 on the shaft 1 and coming from a pulley 93 on thearmature shaft of an electric motor 94, but when the'power is applied tothe other end of the structure then the motor 94 may be replaced by adynamo from which electric current may be taken off.

Upon each shaft 38, 41, 44 and 47, there is a one-way clutch 95 with itscasing provided with a radially extending arm 96 terminating in a weight97 of suitable size though only diagrammatically indicated in thedrawings. Each arm 96 is connected by a link 98 to one end of a lever 99having a suitable fixed support while the other end of this lever ispivotally connected to another lever 100 having a fixed fulcrum supportwhile the free end of the lever 100 is in the path of pins 101 on thehubs of the respective gear wheels 37, 40,43 and 46. When the gearwheels 37, 40, 43 and 46 are rotated then the pins 101 come intoengagement with the respective levers 100 thus'rocking the levers 99 ontheir pivotal supports and elevating the respective weighted arms 96,the clutches then moving idly. As soon as the pins 101 move out ofengagement with the levers 100, then the weights 97 become active tocause a rotative movement of the casings of the clutches 95. and thismovement is transmitted through the ratchet wheels within the casings tothe respective shaft-s 38, 41, 44 and 47 and rotative movement isimparted to the latter in a step-by-step manner, but because of theintermeshingof the gear wheels 37, 40, 43 and 46 the rotative movementof the shafts 38, 41, 44 and 47 will be in opposite directions one withrelation to its neighboring shafts. If the motor 94 be energizedrotative movement is imparted to the shaft 1 and to the fly wheels orinertia members 3 and movement will be imparted to the train of gearwheels 31, 34, 37, 40, 43 and 46 through the gear train 21 to 30inclusive, the speeds of the gear wheels being proportionate to therelative sizes of the several transmission gear wheels. This will causeslow step-by-step rotative movement of the shafts 38, 41, 44 and 47 andthese shafts may be connected to the work to be performed. At the sametime rotative movement is imparted to the shaft 86 by the belt 89 andintermittent rotative movement is imparted to the shafts 82 by themutilated gear wheels 85.

The showing of the drawings is in part diagrammatic, but it will beunderstood that the proportion of the mutilated gear wheels and of thegear wheels or pinions 84 as well as the worms 81 and worm gears 80 issuch that the active portion of each mutilated gear wheel 85 will causethe movement of an arm 78 to an extent sufficient to compress the spring71 through the lever systems 76 and 74 and then before the activemovement of the mutilated gear wheel 85 ceases the lever 76 has escapedfrom an actuating arm 78 and then the spring 71 compressed by the activemovement of an arm 78 is free to expand and so through the arm 67 andcorresponding clutch 54 or 57 impart a rotative movement to the shaft32.

The parts may be so proportioned that a strong impulse is imparted tothe shaft 32 to cause its rotation in one direction by the expansion ofone or both springs 71, depending upon the set of the mutilated gearwheels 85, and then the shaft 32 may be rotated in the oppositedirection by the action of the clutches 55 and 56, and since the returnmovement of the shaft need perform little or no work, the said shaft 32may be connected to work requiring a powerful movement in one directionand a comparatively weak movement in the other direction, and thesemovements of the shaft 32 will in no manner interfere with the continuedthough step-by-step forward movement of the shafts 38, 4'1, 44 and 47,though the rotative move ment of these last named shafts may be inreverse directions, but always in one direction so far as any individualone of said shafts 38, 41, 44 and 47 is concerned.

The present invention is useful in ma chines requiring various andcomplex movements for shaping or bending or both.
